Shows Run: New Girl (2011-Present)
New Girl might be Liz Meriwether's first go-round as a showrunner, but her show's growth during its second season has turned the slow-starter into a critical and fan favorite. Along with Lena Dunham, Veena Sud, and Mindy Kaling, Meriwether is fast becoming an icon for the ever-increasing number of female writers and creators. Though we imagine New Girl is going to enjoy some more shelf life, we look forward to seeing what other projects Meriwether will produce in what looks to be a promising career.
